Trieste (L9890) – a new landing helicopter dock for the Italian Navy that is undergoing sea trials, and is expected to be commissioned in June 2022.
Trieste was built primarily for the transport and landing of troops, military vehicles, logistics equipment, goods and supplies.

The ship has an overall length of 245 m, a beam of 47 m, a depth of 7.2 m, and a fully loaded displacement of 33,000 tons.
Trieste will be equipped with medium helicopters like EH101 and NH90 and Lockheed Martin F-35B Lightning II aircraft. In addition, the Landing Ship will feature a garage deck capable of housing wheeled and tracked vehicles, offering up to 1,200 linear metres of storage. The vessel’s cargo space will be accessible via stern and side ramps, while the internal ramps and elevators will support the handling of cargo on-board.
It will have a floodable well deck below the hangar level able to accommodate amphibious landing vessels such as LCM, LCAC, and newer Landing Catamaran vessels.

A fully equipped hospital will also be available onboard, complete with operating rooms, radiology and analysis rooms, a dentist’s office, and patient rooms capable of hosting 27 seriously injured patients.
The ship will be powered by a COmbined Diesel eLectric Or Gas propulsion system and an additional electric propulsion system to be used for low-speed sailing. The propulsion system will include two Rolls-Royce MT30 gas turbines providing 102,000 hp, two MAN 20V32/44CR diesel engines, four diesel engines generators MAN 9L32/44CR, developing 28,110 hp., two 3,020 hp electric engines, and two shafts. She will be able to reach a top speed of 25 knots with a maximum cruising range of 7,000 nautical miles at 16 knots.
The armament fitted on-board the ship will include three Oto Melara 76/62 Super Rapid gun mounts, three Oto Melara KBA 25/80mm cannons and various 12.7mm small calibre guns. The ship can also be installed with a vertical launch system (VLS) to facilitate the firing of surface-to-air missiles.
